ELECTRIC ClRCUIT CCNNECTION.

, .SPECIPIC'ATION forming part of Letters Patent NO. 371,840, dated October 18, 1887.

(No model.)

To all whom it may conccrm Be it known that we, SAMUEL I-IEFFNER and J OIIN H. PHILLIPS, citizens of the United States of America, residing at Pottsvillc, in the county of Schuylkill and State of Pennsylvania, have invented certain new and useful I111- provements in Electric-Circuit Connections, of which the following is a specification, reference being bad therein to the accompanying drawings.

Our invention relates to an improvementin electric-circuit connections; and it consists in the peculiar construction, combination, and arrangement of theparts, substantially as hereinafter fully set forth,and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a plan view. Fig. 2 is alongitudinal sectional viewshowing the device coupled, and Fig. 3 is an enlarged detail View.

In the construction of our electric circuit connections, which comprises two sections, A and B, similarly made, we safely secure the inner end of each tapering spiral spring 0 to the metallic core or stock D of its section, the outer end of each spiral spring being provided with asuitable abutment-piece, E, which abutment-piece is secured to the front platform of the car. i

The metallic stock D is shouldered at E, where the tapered convolutions of the spring encircle it, abut, and are secured, as aforesaid.

Stock 1) in each corresponding section of the coupling also has rigidly secured thereto the scallop-band E, or said scallop-band E may be cast integral therewith. The latter consists of a series of long scallops, F, flaring outwardly from the band, the scallops in each car-section being arranged to register in such manner as always to interpose a scallop between two corresponding scallops, which, thus ,in presence of two witnesses.

meshed, guide the coupling-sections together and cause the buttons (0, one on either end of the electric wires,to connect, the wires G being projected to their destination through corre- 5 sponding apertures in stocks D. These buttons a, which are rigidly secured, one to the end of each electric wire, may be provided with a flattened contact-surface; or one of the buttons may be slightly concaved, to conform to a cor- U responding convexity formed in the button. Thus constructed and arranged, when the taporing ends of the scallops are brought into contact, although the cars may not be of the same precise height, the scallops and the springs cause the wires to converge together as the cars approach, and thus effect the perfeet coupling of the wires.

\Vhat we claim is 1. In an electriccircuit connection, the combination, with the circuit-wires, of the stocks and the scallops projecting therefrom, substantially as shown and described.

2. In an electriccircuitconnection, the combination, with the circuit-wires, of the stocks, the scallops projecting therefrom, and the springs connected to said stocks and to abutments attached to the cars, substantially as shown and described.

3. The combination of the circuitwvii'es, the P stocks having projecting scallops, thebuttons secured to the opposite ends of said wires, and the springs connected to said stocks, substantially as shown and described.

In testimony whereof we affix our signatures SAMUEL HEFFNER. JOHN H. PHILLIPS.
